Abstract Two new mixed metal cluster complexes PtRu3(CO)10(PPh3)(μ3-S)2,3 14% yield and PtRu3(CO)9(PPh3)2(μ3-S)2,4 23% yield were obtained from the reaction of Ru3(CO)9(μ3-S)2,1 with Pt(PPh3)2(C2H4) at 0°C. The cluster of4 consists of a spiked triangle of four metal atoms with two triply bridging sulfido ligands. The reaction of Ru4(CO)11(μ4-S)2,2 with Pt(PPh3)2(C2H4) yielded the expanded mixed-metal cluster complex PtRu4(CO)12(PPh3)(μ4-S)2,5 in 12% yield. The structure of the cluster5 can be described as a pentagonal bipyramid of five metal atoms and two sulfido ligands with one metal-metal bond missing. Compounds4 and5 were characterized by a single-crystal X-ray diffraction analyses.
